Hello, I’m Dejan

I’m a software developer from St. Pölten, Austria, and my thing is making multiplayer games actually fun to play - not just technically “working.” I focus on gameplay and network programming, because for me the best part of games is when people get to share the chaos together with a server structure that gives players stable connections. I work with Unity, Unreal Engine, C++, and C#, and I’ve got a clear goal: build interactive, scalable multiplayer worlds that keep players hooked. Network protocols, client-server models, dynamic systems — that’s my playground. Right now, I’m working as a Software Developer and steadily leveling up my skills, with my eyes set on creating bigger and better multiplayer experiences. In short: I know where I’m going, and I’m having fun getting there.
